As defined by the National Association of City Transportation Officials, protected intersections create shorter, simpler crossings, more predictable movements, and better visibility between people on bikes and people driving. As a result, the intersection is more comfortable and safer for people using the bikeway and the crosswalk. This design keeps bicycles physically separate from motor vehicles up until the intersection, providing a high degree of comfort and safety for people of all ages and abilities.
This design can reduce the likelihood of high speed vehicle turns, improve sight-lines, and dramatically reduce the distance and time during which people on bikes are exposed to conflicts. For example, in San Francisco, a protected intersection design resulted in 98% of drivers yielding to people on bikes, and 100% yielding to people walking. Please visit our project website for a great 5-minute video highlighting the design features of a protected intersection produced by a Senior Planner/Designer at the City of Portland Bureau of Transportation. http://www.protectedintersection.com/
